Change and Control Paradoxes in Mobile Infrastructure Innovation: The Android and iOS Mobile Operating Systems Cases
2012
The advent of the smart phone as a highly complex technology has been accompanied by mobile operating systems (OS), large communities of developers, diverse content providers, and increasingly complex networks, jointly forming digital infrastructures. The multi-faceted and relational character of such digital infrastructures raises issues around how change and control can be conceptualized and understood. We discuss how change and control are paradoxically related in digital infrastructures and how they affect the evolution of such infrastructures. We examine these paradoxes by examining the change in, and competition between, two mobile operating systems: Apple's iOS and Google's Android a…
Cybersecurity risk assessment subjects in information flows
2022
A modern society includes several critical infrastructures in which digitalization can have positive impacts on the levels of autonomy and efficiency in the use of infrastructure systems. Maritime transportation is an example of an infrastructure that currently needs development in the digitalization of its operations and processes. At the same time, maritime processes represent a large-scale cyber environment, thus trustable information distribution between system elements of the processes is needed. Since 2020, the Sea4Value / Fairway (S4VF) research program in Finland has been working to develop maritime digitalization which can lead to autonomy processes in the future. The first stage o…
Assessment of Cybersecurity Risks: Maritime Automated Piloting Process
2022
A modern society is a combination of several critical infrastructures, of which international and national maritime transportation systems are essential parts. Digitalization makes it possible to increase levels of autonomy in maritime systems. It also means fully existing cyberenvironments in maritime processes. In cyberenvironments, it is crucial there is trustable information communication between system elements of the process, alongside the usability, reliability, and integrity of systems data in the operating environment. In order to develop maritime autonomy in Finland the Sea4Value / Fairway (S4VF) research program has been developed. At the first stage of the program, the main goal…
Struktuurit ja pelit kielenoppimisen alkuvaiheen tukena
2019
Vastaantulo-hankkeessa on perehdytty kielenoppimisen alkuvaiheeseen ja suullisen kielitaidon kehittymiseen valmistavassa opetuksessa. Oppilaan aloittaessa koulunkäynnin uudella kielellä, on kielenoppimisen kannalta merkityksellistä päästä osallistumaan vuorovaikutukseen luokkatovereiden ja opettajien kanssa sekä oppia vuorovaikutuksessa relevanttia, autenttista ja merkityksellistä kieltä. Tässä artikkelissa tarkastelen struktuurien ja vuorovaikutukseen ohjaavien pelien merkitystä kielenoppimisen alkuvaiheessa olevan oppijan suullisen kielitaidon kehittymisen kannalta. Tarkastelu pohjautuu Vastaantulossa alakoulun valmistavan opetuksen ryhmässä kuvattuun videomateriaaliin sekä pro gradu -tut…

Insecure Firmware and Wireless Technologies as “Achilles’ Heel” in Cybersecurity of Cyber-Physical Systems
2022
In this chapter, we analyze cybersecurity weaknesses in three use-cases of real-world cyber-physical systems: transportation (aviation), remote explosives and robotic weapons (fireworks pyrotechnics), and physical security (CCTV). The digitalization, interconnection, and IoT-nature of cyber-physical systems make them attractive targets. It is crucial to ensure that such systems are protected from cyber attacks, and therefore it is equally important to study and understand their major weaknesses. peerReviewed

Enhancing the European Cyber Threat Prevention Mechanism
2021
This research will determine how it is possible to implement the national cyber threat prevention system into the EU level Early Warning System. Decision makers have recognized that the lack of cooperation between EU member countries affects public safety at the international level. Separate operational functions and procedures between national cyber situation centers create challenges. One main problem is that the European Union does not have a common cyber ecosystem concerning intrusion detection systems for cyber threats. Also, privacy and citizens’ security as topics are set against each other. The research will comprise a new database for the ECHO Early Warning System concept.
